Bob-
  I sent my KPC9612 back to Kantronics today for warranty fix of software
carrier detect.  If you have used SW DCD, did you have any problems?
(This would, of course, be only on port 1 - 1200).
  The unit is very nice and gets two thumbs up just as my KPC3 does.

Probably the biggest plus of the stand-alone TNC is that your station can be
on the air when your computer is not up.

As for 9600 operations, you need to find out if there are plans in your area
(unless >you< are a mover and shaker) to put up some 9600 baud resources.
Getting going on 9600 is not as easy as 1200.  You either have to have 1) a
radio specificly designed for 9600 operation, or 2) a willingness to do
radio surgery to bring out the connection points required for 9600
operation.

What this usually involves (at a minimum) is providing connections to the
discriminator (or FM IF/detector chip) and into a place in the radio where
direct FM modulation can be done.  Many radios now use the phase-locked loop
(PLL) as the modulation point.  Unfortunatly, because of the nature of
PLL's, they are designed to correct for frequency errors they find.  In the
case of 9600 baud operation, you are no longer putting tones on an FM audio
channel.  You are acutally putting 'raw' data on the modulator.  This means
that for desired operation, that the modulation point needs to have flat
frequency response from about 10 Hz to 5 kHz.  Most PLL's have a 3dB
highpass effect at about 100-200 Hz.  As yet there is no easy solution to
the problem, so some rigs will just work better than others.  If you still
plan on getting a 9600 baud TNC, call the manufacturers of the products you
are considering and ask them 1) about specific radios you may have now, and
2) radios they might suggest as good choices.  Until about 6 months ago I
worked for one of the TNC manufacturers (AEA) and know that they are very
interested in developing information about what works and what does not.

Subject: Help, connecting ethernet to JNOS..
To: [e-mail]

Hello, I have bin trying to connect a computer running JNOS 1.10d
to an TCP ethernet LAN, without any luck. I'm using an
Novell NE2000 with a Crynwr packet driver. The commands I put
in the autoexec.nos are basically the attach command and few
ifconfig commands, It is based on the WJ7J configuration file
witch I got in a help packet from some ftp site.

The problem is I can't Telnet, Ftp or ping any comuters, witch are
on the same LAN, or other computers on Internet. So It must be
something wrong with the driver or how Im configuring JNOS.

So please if you can assist me in any way,
it would be greatly appreciated

... any autoexec.nos examples would be appreciated.

please post or e-mail.

tnx in advance

To: [e-mail]

Wouldn't be a bad idea to replace the battery unless you intend on
running the tcp/ip on a full time basis as you have to operate tcp/ip in
the "Kiss" mode. I have been using my PK232mbx ever since I bought it
back in 1989 with the battery installed and never had a bit of problem.
Good luck and let me know via email how you make out

In keeping with the thread... I am using an LC with a  kantronics KPC-2
hooked to the printer port... The station runs on Red Ryder 10.3 which is
available at many ftp sites. I got my initial packetsettings from AOL in
the Ham radio area... ?'s  drop me a note, you will get a faster response
with e-mail as I omnly check the newsgroup once or twice a week  :-)

Subject: TCP/IP over packet trough winsock ...
To: [e-mail]

I've just tried the modified Crynwr driver, called ethrax25.
This should allow me to use tcp/ip through windows sockets.
I tried it, and everything seems to start.
I used the latest version of Trumpet winsock, and the latest version
of ws_ftp.  If I try the FTP, the TNC does transmit something, but
the trumpet winsock stuff immediatly gives an ARP time out, and
a TCP error.  It also stops retrying very soon.
Has anyone got experience with this?

Thanks in advance

Subject: TEKK MINI for 19k2 ??
To: [e-mail]

Hello all.

I'we heard lot about this TEKK MINI 70cm crystal rx/tx.
It appears that it is ready to go to 9k6, but what about
19k2, is it hard to get it up that speed. I assume you have
to do something about the IF filters, so is it hard or
expensive to get new filters for that station and is it
hard to replace them.

Any input welcome..

For radios I have sucessfully used:
Icom IC-290 (the first radio I modified)
Icom IC-22S (uses diode matrix synthsizer in 15 kHz steps.  Designed for
146-148, tho usually goes to 145.35 or so OK.)
GE MVP (high band VHF - xtal controlled, easy to modify)

I currently use the GE on the local 2M packet repeater, as I hope one day to
get the IC-290 back on SSB.  The IC-22S is probably going to get modified to
20 kHz channel spacing and to cover the whole 2M band.  Then it will
probably go into my (ever evolving) portable packet station.

Hope that gives some insight on 9600 operations.

Possibly you are correct in watching the term, but it is not broadcasting
in the sense of the ARRL's broadcast of "code practice and such".  This
is a network broadcast.  It is a transmission to a special address that
can be received by more than one station.  It is still usually sent to
some "callsign" (in the IP world that call is usually QST for AX.25).  It
also implies that there is no acknowledgement of receipt.
If you are concerned about getting a NAL over this, you had better make
sure that you don't have your TNC setup to do a beacon or even ID itself
regularly as these are the same type of things.
